Specification of Letters'Pimenty i Patented lrly 8, 1913.

Application filed March 21, 1912,`.Seria1.No. 685,188. Renewed- March 27, 1918. Serial No. 757,258.

To all whom t may concern: Be it known that I, 4Jorma HAROLD ENG- BERG, a citizen of the United States, residing at Braham, in the county of Kanabec, 1n

pointed out inthe claims and illustrated in the accompanying drawings which form a part of the specification', and in which- Figure 1 isa 'side elevation of my im.-

proved wind wheel and governor. Fig. 2 is a similar view partly 1n section. Fig. 3 1s a rear plan ofthe device. Fig. 4 is a plan of a detail. Fig. 5 is a oreshortened perspective of one of the wings. Fig. 6 isa front 'plan of a portion of the wind wheel showing the wings in their inoperative position. Figs. 7 and 9 are views of opposite sides of a wing. Fig. 8 is a detail o the governor gear. F ig.'10 is a view of a portion of one wing on edge.

y Like reference characters lndicate correlaponding parts throughout the several views.v

1 is the shaft or axis upon .which my wind wheel is .supported and which likewise carries the pump rod eccentric 2, when the device is used as a wind pump, and the governor 3. The loose governor-keeper 4 is slotted as at 5 and a pih 6 aixed inthe vshaft l extends through the slot.5 andfpermits reciprocation of the keeper upon the shaft. The keeper 4 is provided with ears 7, 7 that are pin-connected to the slotted extremity of bell cranks 8, 8 the apex of each of which is pivoted to rods 9, 9 connected,

by pins 10, 10 to the inner periphery 11 of a hub 12 mounted upon the shaft l; 13 is a collar secured to the shaft 1 upon the governor side of the hub and 14 isa nut secured upon the threaded extremity of the shaft 1 at the other side of the said hub..

Upon the back of the hub 12 spokes 15, 15 are secured and to them one end of either spring 16, 16 is secured, the other end of the springv being fastened to a lug made integral with the ears 7 of the governorkeeper 4.

The several spokes in the wheel extend from the hub 12 to which they are secured by bolts 18 outwardly to a front wheel rim 19 which is provided with a plurality of integral back-projecting apertured lugs 20 and between the front wheel rim and the hub 12 a plurality of wings 23 are supported upon suitable pivots-as shown in Fig. 5. is a rear wheel rim formed with a pair of oppositely disposed racks 22, 22 upon its inner periphery. r1he width of each wing .23 increases as it extends from the hub 12 to the rim 19 and at this rim one corner of each wing is offset and provided with a mejtallic loop 17 disposed in a plane' at right angles to the body of the wing. Two of the wings 23 disposed opposite each other are not pivotally connected to the rim 19 but are each connected by links 24', 24 to the two adjacent wings 23 and by them operated. This construction is necessary to permit the operation of the tWo-one-pivot wings just described past gear wheels 24, 24a the axes 25, 25 of which are secured to angle pieces 26, 26 to which pieces the outward terminations of the several spokes 15 are also secured. Arms 27, 27 have one end secured to the faceof one gear Wheel 24a near its outer edge, the other end of the said arms being secured to the upper termination of' lthe bell cranks 8, 8.

The outer periphery of the rear wheel rim 21 is provided with al lurality of apertures 28 through which` pins 29 extend for engagement with the loops 17 of the wings 23.

Operation: The rotation or operation of the entire wind wheel is caused by the wind blowing against the'face of the device when the Wings overlap as shown in Fig.3. \Vhen a gale of wind causes the device to rotate at a dangerous speed or at such a speed as to cause dan er of breakage of its lparts the governor will assume the position shown in dotted lines which will draw the keeper 4 back toward the governor against the tension of the springs 16, 16 thusrotating the bell cranks into the position lshown dotted which will cause the arms 27, 27 to so actuate the gear wheels 24, 24l as to force the rear wheel rim 21 to rotate suiiciently to throw the said wheels 241to the opposite end of the rack 22. This movement ofthe rim 21 is in a plane parallel with the plane of the rim 19 and is independent of that rim and the result of this movement is to greatly reduced) and as the speedl becomes normal the springs 16, 16 will draw the governor back into its normal position,

shown in full lines, when the other parts of the device will assume their normal positions.

Vhat is claimed is 1.` In a mechanism of the class described the combination with a revoluble shaft provided with a governor having one movable keeper, of a hub mounted onsaid shaft, rods carried by said hub, bell cranks pivotally secured to said rods and operatively connected to the said governor keeper, spokes secured to said hub, angle pieces terminally carried by said spokes, oppositely disposed gears pivotally carried by oppositely dis* posed angle pieces, arms connecting the said gears and the aforesaid bell cranks, a rear wheel rim formed with oppositely disposed interior racks for engagement with the said gears, a front wheel rim formed with inte gral lugs, wings, formed with loops, pivotally connecting the said front wheel rim and the aforesaid hub, pins carried by said rear Wheel rim engaging the looped portions of the said Wings and means connecting the said governor keeper and the said spokes for returning the mechanism to normal position after that position hasvbeen disturbed.

. 2. .In a mechanism ofthe class described the combination with a revoluble shaft provided with a governor having one movable keeper, of a hub mounted on said shaft, a nut terminally carried by said shaft, rods carried by said hub, bell cranks pivotally secured to the said rods and operatively connected to the said governor keeper,

spokessecured to said hub, angle pieces terminally carried by said spokes, oppositely disposed gears pivotally carried by two of the said angle pieces, arms connecting the said gears and the aforesaid bell cranks, a rear wheel rim formedwith oppositely disposed interior racks for engagement with the said gears, a front wheel rim formed with integral lugs, wings, formed with loops, pivotally connecting the front rim andthe aforesaid hub, pinsv carried by said rear Wheel rim 'engaging the looped portions of the said wings and a spring connecting'the said governor keeper and spokes.

3. In a mechanism of the class described the combination with a revoluble shaft provided with a governor having oneI movable keeper, of a hub mounted -on said shaft, a

nut terminally carried by said shaft, rodsv carried byl said hub, bell cranks pivotally secured to said rod and operatively connected to the said governor keeper, spokes -secured to said hub, angle pieces terminally carried by said spokes, oppositely disposed gears pivotally carried by two of the said angle pieces, arms connecting the said gears and the aforesaid bell cranks, a rear Wheel rim-,formed with oppositely disposed interior racks for engagement with the said gears, a front wheel `rim formed with. in-
